- Environmental Bioconcentration: An estimated BCF value of 33100 was calculated for bis(2-hydroxy-3-tert-butyl-5-methylphenyl)methane(SRC), using an experimental log Kow of 6.25(1) and a recommended regression-derived equation(2). Bioconcentration factors of 23-37 and 60-125 were obtained during an 8 week bioconcentration study using carp and bis(2-hydroxy-3-tert-butyl-5-methylphenyl)methane concentrations of 1 and 0.1 mg/l, respectively(1). According to a recommended classification scheme(3), the experimental BCF values suggest that bioconcentration in aquatic organisms will be moderate to high(SRC). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: TERRESTRIAL FATE: Based on a recommended classification scheme(1), an estimated Koc value of 59800(SRC), determined from an experimental log Kow(2) and a recommended regression-derived equation(3), indicates that bis(2-hydroxy-3-tert-butyl-5-methylphenyl)methane will have no mobility in soil(SRC). Volatilization of bis(2-hydroxy-3-tert-butyl-5-methylphenyl)methane may not be important from moist soil surfaces(SRC) given an estimated Henry's Law constant of 7.9X10-12 atm-cu m/mole(4,SRC), or from dry soil surfaces(SRC) based on an estimated vapor pressure of 2.5X10-9 mm Hg(5,SRC). Based on a MITI biodegradation test, bis(2-hydroxy-3-tert-butyl-5-methylphenyl)methane will not biodegrade in soil(2). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: AQUATIC FATE: Based on a recommended classification scheme(1), an estimated Koc value of 59800(SRC), determined from an experimental log Kow(2) and a recommended regression-derived equation(3), indicates that bis(2-hydroxy-3-tert-butyl-5-methylphenyl)methane will adsorb to suspended solids and sediment(SRC) in the water. Bis(2-hydroxy-3-tert-butyl-5-methylphenyl)methane should not volatilize from water surfaces based on an estimated Henry's Law constant of 7.9X10-12 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). Experimental BCF values of 23-37 and 60-125 at 1 and 0.1 mg/L(2), suggest that bis(2-hydroxy-3-tert-butyl-5-methylphenyl)methane will bioconcentrate in aquatic organisms(SRC) according to a recommended classification scheme(5). Based on a MITI biodegradation test, bis(2-hydroxy-3-tert-butyl-5-methylphenyl)methane will not biodegrade in water(2). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: ATMOSPHERIC FATE: According to a suggested classification scheme(1), an estimated vapor pressure of 2.5X10-9 mm Hg at 25 °C(2,SRC) indicates that bis(2-hydroxy-3-tert-butyl-5-methylphenyl)methane will exist in the particulate phase in the ambient atmosphere. Particulate-phase bis(2-hydroxy-3-tert-butyl-5-methylphenyl)methane may be physically removed from the air by wet and dry deposition(SRC). Source: Hazardous Substances Data Bank (HSDB)
